2 Introduction CAEN has developed a complete family of digitizers that consists of several models differing in sampling frequency, resolution, number of channels, form factor, memory size and other parameters. The following table lists all models currently available. In parallel with the hardware development, CAEN has made a big effort in developing algorithms for the Digital Pulse Processing (DPP); the user can install a DPP algorithm on the FPGA of the digitizer (firmware upgrade), run it on line and implement new acquisition methods that go beyond the simple waveform recording. A digitizer with DPP becomes a new instrument that represents a fully digital replacement of most traditional modules such as Multi and Single Channel Analysers, QDCs, TDCs, Discriminators and many others.

3 Principle of Operation The basic operating mode of a digitizer is essentially the same as a digital oscilloscope: the analog signal, after an input stage of signal conditioning mainly used to adapt the dynamic range, is sampled by a flash ADC, whose output, i.e. the stream of digital samples, is continuously read by an FPGA and stored in a circular memory buffer of a programmable size. At the arrival of the trigger, the buffer is frozen and made available for the readout while the acquisition can continue in a new buffer.. However, there are few important differences between a digitizer and a commercial digital oscilloscope:: 1 The digitizers allow for dead-timeless acquisition. In fact, unlike most oscilloscopes, they have the ability to accept two consecutive triggers very close to each other (1) thanks to the multi buffer memory management: there is no dead time between an acquisition window and the next one. It is even possible to accept two trigger for which the acquisition windows overlap. The dead-timeless acquisition is a very important feature, especially in the case of events randomly distributed in time (in nuclear physics this is typically a Poissonian distribution), so that two of them, even at low rate, can occur at very short distance but you still want to capture both. (1) Except for 742 and 743 Series. 2 In the digitizers, all the channels are allowed to generate triggers independently. The individual trigger can be used locally by the channel that generated it (independent triggering) or can participate to the assertion of a global trigger for all the channels in the board, as well as to generate a pulse on the TRG-OUT. 3 The digitizers are designed for scalability. It is possible to synchronize several boards to make an acquisition system with a theoretically unlimited number of channels. Board synchronization consists in distributing a common clock reference on which all the ADC sampling clocks are locked, aligning the acquisition time base of each board in order to have events with correlated time stamps, distributing the channel auto-triggers and the global triggers according to a programmable trigger logic in order to implement coincidences, neighbour triggering and other acquisition criteria and topologies. 4 The High bandwidth data readout links. Usually oscilloscopes do not have any communication channel (data is only displayed) or, if they have, most probably it has a fairly low bandwidth (GPIB, Ethernet, etc ); conversely, the digitizers are designed to provide high rate data transfer to a computer or an external data processing unit. CAEN digitizers have a minimum bandwidth of 30MB/s in the case of the USB, about 80MB/s with CONET port up to more than 120MB/s for the VME with 2eSST. 5 On Line data processing. Thanks to the FPGAs housed in the digitizers, CAEN developed on-line digital algorithms for signal processing. This feature allows the implementation of systems that are not simply based on the acquisition, storage and readout of waveforms (raw data) but rather on the calculation of the quantities of interest and the storage and transfer of just the final results, with clear advantages in terms of readout bandwidth.

4 Digital Pulse Processing (DPP) for physics and biomedical applications In recent years, thanks to the availability on the market of faster and more precise ADC chips, several applications in nuclear physics (or related fields) have made large use of data acquisition systems based on digitizers. However, systems based on digitizers could have a basic fundamental issue: the extremely huge amount of data to manage. For this purpose, special algorithms can be applied to the digital samples for the extraction of the quantities of interest and the reduction of the data, therefore performing an on-board Digital Pulse Processing (DPP). The relevant digital filters are, in most cases, very similar (at least from a functional point of view) to the old and familiar analogue circuits, such as timing filters, shapers, CFDs, baseline restorers, etc The benefits of the digital approach are great stability and reproducibility, ability to reprogram and tailor the algorithms to the application, ability to preserve the information of the signal along the entire acquisition chain, flexibility, better correction of baseline fluctuation, pile-up, ballistic deficit, etc All this in one board CAEN One single board can do the job of several analog modules Full information preserved Reduction in size, cabling, power consumption and cost per channel High reliability and reproducibility Flexibility (different digital algorithms can be designed and loaded at any time into the same hardware) To cover most of the applications, CAEN developed four main DPP firmware: DPP-PHA for Pulse Height Analysis: available for the 724 and 730 (*) families, the digitizer running DPP- PHA firmware accepts signals directly from Charge Sensitive Preamplifiers or photomultiplier tubes and implements a digital replacement of Shaping Amplifier and Peak Sensing ADC (Multi-Channel Analyser) by means of digital trapezoidal filters. (*) x730 compliant version COMING SOON DPP-CI for Charge Integration: available for the 720 family, the digitizer running DPP-CI firmware is well suited for data acquisition and processing of signals from scintillators/photomultipliers or SiPM detectors, implementing a digital version of the traditional QDC (Charge-to-Digital Converter). DPP-PSD for Pulse Shape Discrimination: available for the 720, 751 and 730 families, the digitizer running DPP-PSD firmware accepts signals directly from the detector and implements a digital replacement of dual gate QDC, discriminator and gate generator. DPP-ZLEplus for the Zero Length Encoding: available for the 751 and 730 familes, the digitizer running DPP-ZLEplus allows the user to transfer the digitized waveforms in compressed mode, performing an enhanced Zero Suppression algorithm on the input signals. Trigger and synchronization in multi-board systems In most cases, the applications that require the use of several channels need to synchronize the acquisition across different digitizers. This is performed according to the following points: Distribution of a common clock reference in order to have the same sampling clock on all the ADC channels. CAEN digitizers feature a programmable PLL able to generate the sampling clocks locked to an external clock input, whose distribution can be done in parallel from a common source, using a fan-out, as well as through an in-out daisy chain with the ability to use the first board as a clock master (VME models only). Alignment of the time stamp associated with the triggers to allow off-line reconstruction of the events read from different boards. This can be done by using an external signal as well as through an in-out daisy chain. Distribution of the triggers from channel to channel and from board to board, according to a certain trigger logic. Each card has different trigger sources: external TRG-IN from the front panel, software trigger and channel self- triggers. All these triggers can be combined in order to make coincidences, majorities, global triggers and other functions. 4 GD Introduction to Digitizer

5 Application Notes CAEN provides a wide selection of application notes, white papers and scientific articles focused on digitizers and their use in different fields. In these documents, the capability and flexibility of CAEN digitizers are well exploited showing their physicsdriven development. Here follows a brief selection: AN2086 Synchronization of CAEN Digitizers in Multiple Board Acquisition Systems. This Application Note shows how to synchronize two or more homogeneous CAEN digitizers in a multi-board acquisition system. We describe the steps needed to synchronize a simple system, composed by two V1720 digitizers in three different hardware set-up which can be easily generalized to more complex cases. AN2503 Charge Integration: Analog Vs. Digital The aim of this application note is to compare the energy resolution of two gamma ray spectroscopy setups based on two different acquisition chains the first uses an analog V792N QDC, the other based on a 12 bit, 250 MS/s V1720 digitizer with a Charge Integration Digital Pulse Processing (DPP-CI). AN2506 Digital Gamma Neutron discrimination with Liquid Scintillators In this application note, we describe the capability of the 720 Digitizer family (12 bit, 250MS/s) to perform neutron-gamma discrimination based upon the digital pulse shape analysis. The digitizer runs the preliminary version of the DPP-PSD firmware for the digital charge integration and neutron-gamma discrimination. AN2508 CAEN Digital Pulse Height Analyser a digital approach to Radiation Spectroscopy The aim of this application note is to show the principles of operation and the results obtained in high resolution gamma spectroscopy using CAEN Digital Pulse Height Analyser, a dedicated system based on x724 digitizers and DPP-PHA firmware. WP2081 Digital Pulse Processing in Nuclear Physics This White Paper explains the possibilities offered by Digital Pulse Processing algorithms in Nuclear Physics applications: Pulse Triggering and Timing Filters, Pulse Height Analysis (DPP-PHA - Digital MCA), Charge Integration (DPP-CI - Digital QDC), Pulse Shape Discrimination (DPP-PSD - Neutron/gamma Discrimination), Time measurements. AR2614 Tests of PMT Signal Read-out in a Liquid Argon Dark Matter Detector with a New Fast Waveform Digitizer V bit 2/1 GS/s Digitizer digitizer provides a very good (relatively low-cost) solution for data acquisition in Dark Matter searches using PMTs to detect scintillation light in liquid argon. arxiv: v2 [astro-ph.im] Published in Journal of Instrumentation DOI: / /7/07/P07003 AR2613 Special nuclear material detection with a mobile multi-detector system The detection of special nuclear material has been studied with a mobile inspection system used both as a high sensitivity passive neutron/gamma spectroscopic tool and as an active inspection device using tagged neutrons. The detection of plutonium samples seems to be possible with passive interrogation, even for small samples. The passive detection of uranium is much more difficult because of the low neutron yield and of the easiness of shielding the gamma ray. However, we show that active interrogation with tagged neutrons is able to provide signatures for the discrimination of uranium against other heavy metals. AR2612 First demonstration of a Compton gamma imager based on silicon photomultipliers Development of a rugged and person-transportable Compton gamma imager for security investigations of radioactive materials, and radiological incident remediation. The imager is composed of layers of scintillator with light collection for the forward layers provided by SiPMs and for the rear layer by PMTs. Signals from both the SiPM pre-amps and the PMTs are processed by CAEN V1740 digitizers. arxiv: v1 [physics.ins-det]. Nucl. Instr. and Meth.
